Biodegradable surfactants are surface-active agents that can break down naturally in the environment. Unlike traditional surfactants, which may persist and cause pollution, these eco-friendly alternatives are designed to decompose into harmless substances. They are commonly used in cleaning products, personal care items, and industrial applications. These surfactants are derived from natural sources, such as plant oils or animal fats, making them more sustainable. Their ability to reduce surface tension helps improve the effectiveness of cleaning agents while minimizing environmental impact. As a result, biodegradable surfactants are increasingly favored in the push for greener products.
